METHOD or srmonve PAPER obi-ans, TUBES; Ann LEI-I132"-JZiILhKE Application filed April 26,

This present invention relates to certain new and useful improvements in the methodof splicing paper cores, tubes and the like.

The primary object of the invention resides 6 in the provision of the method ofisplicing able number of paper cores, tubes and the 7-15 like now discardedvmay be redeemed and employed as full length cores, tubes and the like.

A further object of the invention resides in the provision of the method of splicing I paper cores, tubes and the like," whereby the desired length ofcore, tube or the like may be readily produced from a number of shorter sections firmly spliced together.

A still further object of the invention resides in the provision of the method of splicingvpaper cores, tubes and the like, whereby ly connected at'the minimumcost and expenditure of time and labour; A still further object of'the invention resides in the provision of the method'ot splicing paper cores, tubes and the like in a simple and efiicient manner and without waste of time or material and without decreasing the length of the sections'by'cutting'ofi the. opposing ends ofthe'sections to be connected;

A still further object of the invention resides in the provision of the method of splicing paper cores, tubes and the like, without requiring an expensive and complicated machine, tools or other mechanism and skilled workmen for redeeming and splicing. together odd and discarded sections of'paper cores, tubes and the like.

To the accomplishment of these and related objects as shall become apparent as the description proceeds, my invention resides in the construction, combination and arrange 1 ment of parts as shall be hereinafter H more fully described, illustrated in the-accompanydicated by the arrows. the sections may be readilysp'liceda'nd firm- 1930, Serial no; 447,619.

ing drawings and pointed out in the claims hereunto appended; j

The inventionwill be bestunderstood and can be more clearly described when reference is had to the drawings forming a part of this disclosure, wherein like-characters indicate like parts throughout 'theflseveralviews;

FigureBis a'view similar toFigure 1, showing amodified-form of the invention em- 'ployingYthe adjustable transversely" split splicing band p Figure 4 is an elevation ofthe-spliced sections-with the splicing band thereon and Figure '5" 1S3? fragmentary transverse'sec- :tion, taken substantially on the plane'of line 5-5 of Figurel, lookingin -the'direction in Referring more in detail to the drawings, itis tobe' noted that the core ortubesections 11 to be: spliced together have their opposed ends 12 which are to be connected reduced in their exterior diaineter as by squeezing: or

compressing the ends when the cores or tubes are formed of paper, a composition or other' material whichwill' permit such. compression, orfby cutting away a portion of :thematerial on; the 'outer'face' when saidfcoresior' tubes are forinedmt metal or' s'imilari'material which cannot be reduced in its exterior diameter by compression; A series of inwardly directed pockets 18 are-then'provide'd in the reduced'ends 12,; leaving betweensai'd pockets 13 a corresponding number of arcuate extensions 14. with their longitudinal walls. serving also" as the 'longitudin'al walls of the pocketslg and lying in planes radiallyof the cores or tubesas" well as 1on gitudinally thereof. As the' opposed: ends of the cores or tubes 11 ,aresiinilarly' cut, the arcuate' extensions 14" of each of said tubes 11 "will "fit in the. pockets'13 of the other section 11. The pockets13 are of such a depth as to determine a short distance outwardly of the main or non-reduced portion of the cores or tubes 11, thus presenting reduced ends 12 of a greater length than the pockets 13 and the arcuate extensions 14. A splicing band 15 is employed which fits snugly over the reduced ends 12 of the core or tube sections 11, completely covering the arcuate extension 14 as well'as the pockets 13. In

assembling the sections 11 in this manner,

the outer faceof the reduced ends 12 and the walls of the pockets 13 and arcuate extensions 14, should be coated with glue or the like, except on the inner face of the core or tube sections 11. The inner face of the continuous band 15 should also be coated with glue or the like and this band then forced onto the reduced end 12 of one of the core or tube sections 11. The reduced end 12ofthe other core or tube section 11, should then be forced into the continuous band 15 and turned'in such a manner as to permit the arcuate extensions 14: to move into the pockets 13 of the first core or tube section 11, thus firmly uniting the core or tube sections 11 with the outer face of the continuous band 15 flush with the outer face of the said core or tub tube sections 11. When the glue has thoroughly hardened and set, the core or tube sections 11 will be permanently spliced together and the complete core or tube of the required length thus completed from the waste or discarded core or tube sections 11.

In the modified form disclosed in Figures 3 to 5 inclusive, a transverselysplit splicing band 16' is employed in place of the continuous band 15. p This split band 16 has a series of teeth 17 bent inwardly from one wall 18 of the transverse split thereof for engagement between the opposed longitudinal walls of adjacent or interlocking arcuate extensions 14; of the assembled core or tube sections 11, while a tongue 19 is provided on the opposite wall 20 of the transverse split, with side wings 21 on the tongue 19. This second end of the transversely split band 16' is adapted to overlap the first end and permit the side wings 21 of the tongue 19 to be extended through the parallel slits 22 in the-band 16,

adjacent the first mentioned end thereof, as

the band 16 is tightened around the reduced ends 12 of the core or tube sections 11, after connection of the core or tube sections 11 with one another and interlocking of the arcuate extensions 14 of the core or tube sections 11 and the pockets 13 thereof. The

. band 16 is also securely fastened in position on the reduced core ends 12, as it is tightened more rollers, one of which is provided with circumferential series of spaced teeth which serve to punch inwardly through the band ,holdtogether the "interlocked reduced ends 12 of the core or tube sections 11.

As the construction of the device has thus been describedin detail, brief reference is now had to its use and modus operandi: Any de-' sired length of core or tube may be produced frorn waste sections of oddlen'gths by re duclng and cutting one end of each of the sections to provide the pockets 13 and arcuate extensions 1 1 thereon and then connecting M the sections by means of the band 15 or the band 16, in the manner previously set forth. In either form, the band 15 or 16 hasits outer face flush with'the core or tube sections which it serves to unite .and hold together. also apparent that turning of one of the sections, independently of the other is prevented by the interlocking of the arcuate extensions 1 1' of the two sections 11 as well] as byotheband 15 or 16. By seclecting' the proper:

sections 11 a core or tube of any predeter mined length may be readily built up, with out waste. Should it be found necessary to cut off a portion of one of the selected sections 11, this cut off portion may be spliced to another section, when required.

Fromv the" foregoing description, taken in It is connection with the accompanylng drawings,

it will be manifest that mean-sfor and method of splicing paper cores, tubes and'the like, a

is provided that will fulfill all the necessary requirements of such a device, but as many changes could be made in the above description and many apparently widely different embodiments of my invention may be constructed within the scope of the appended claims without departingfrom the spirit or scope thereof, it is intended that all matters contained in the said accompanying specification and drawings, shall be interpreted 1115 as illustrative and not in a limited sense? Having thus described invention, what I claim as new and desire to secure by Letters Patent is 1. The method of splicing paper cores,

tubes and the like including preparing opposed ends of core or tube sections-for interlocking engagement; and applying a band over'said ends. I J

' 2. The method of splicing paper cores, tubes and the like including the preparation of opposed ends ofcore or band sections for interlocking engagement; and

applying a band over said ends with the outer face of said band flush with the outer face of the main portions of said sections.

3. The method of s licing paper cores, tubes and the like inclu ing the reduction of the exterior diameter of opposed ends of core or tube sections; interlocln'ng said ends; and applying a band around said ends with the outer face of the band flush with the outer face of said sections.

4. The method of splicing paper cores, tubes and the like including reducing and recessing the ends of opposed core or tube sections; interlockin of said ends; and securing a band aroun said ends.

5. The method of splicing paper cores, tubes and the like including reducing the exterior diameter of opposed ends of core or tube sections; reoessing a portion of the. reduced ends and interlocking said ends; and securing a band around the reduced interlocked ends of said sections. 7
